Being a toddler, Ariel doesn't have a prominent role in the Veronaville story-line. Her bio states that she doesn't want to get lost in the large amount of people in the house. Because she has no defined personality nor prominent role, she can basically grow up to be anything the player wants her to be, though many players make her a FortuneSim because that seems to be the Capp's dominant aspiration. She has not learned any of the toddler skills.

Once Ariel ages into a teenager, she will have mutual feelings for both males and females. This means that she will become bisexual. However, it's up to the player to decide what sex she will go out with.

Ariel and Beau Broke are the only pre-made toddlers in The Sims 2 base game. Even though Ariel has blonde hair, her dominant genetics are for red hair, while her recessive genetics are for blonde hair. She also has recessive genetics for grey eyes.

It is unexplained how Ariel has top fitness at the start of the game, since it is impossible for toddlers to work out. It is likely the developers made her fit in terms of consistency with other members of the Capp family.

When editing in SimPE, Ariel's zodiac sign is not recognized. This could explain why she doesn't have a zodiac sign mismatch in-game like most pre-made playable Sims from the base game do.

Ariel is a spirit, controlled (but eventually freed) by Prospero in Shakespeare's The Tempest.
